Title: let StringInquirer match _or_ separated multiple words

I'm sort of tired of writing codes like this:

```ruby
if Rails.env.development? || Rails.env.test?
...
end
```
I want StringInquirer to comprehend what I mean by this:

```ruby
if Rails.env.development_or_test?
...
end
```
so, here's the patch.
